Site isolation helps keep most of your data out of reach from hackers looking to exploit the Spectre vulnerability.

Google has introduced a new feature to protect the users of its Chrome browser from a Spectre-type attack. The tech giant made the announcement in a blog post on Wednesday.

The latest iteration of the browser, Chrome 67, will be employing Site Isolation. So, what is it?

"Site Isolation is a large change to Chrome's architecture that limits each renderer process to documents from a single site. As a result, Chrome can rely on the operating system to prevent attacks between processes, and thus, between sites," the blog post explains.

So if a Spectre attack does occur, there's going to only be limited amounts of information available to an attacker.

A single page may now be split across multiple renderer processes using out-of-process iframes. (Google)

Chrome users shouldn't notice anything too different as they browse the Internet day-to-day. There will, however, be a 10 to 13 percent memory overhead, as the site isolation process runs on the browser.

Mobile users won't be left out either. Chrome 68 for Android will be adding a feature similar to the desktop version.
